Does anyone have a solution to make sure your tie off knots don't slip when stringing at high tensions (+26lbs) with Victor VS-850? I have had no issues when using VS-800... but with the 850, I would release the clamps after a tie off and notice a slight slip which (for example) makes the last main lose a pound or two... I'm most concerned about what knot you guys are using... what's the secret?! It's such a slippery string! Thanks all.
